Abstract

Background

Neurons, distributed throughout the body, regulate various bodily functions. The recovery of the nervous system is often slow and can be irreversible. Currently, the approach of using mesenchymal stem cells (MSCs) in conjunction with conventional treatments for nervous system injuries is being explored. Nanoemulsions are systems designed for the nanoscale delivery of drug cargoes. Foeniculum vulgare (F. vulgare), a medicinal plant long utilized in complementary medicine, is the focus of this study. The aim is to utilize nanoemulsions of fennel to induce the differentiation of MSCs into neural-like cells in vitro.

Materials and methods

Human adipose-derived mesenchymal stem cells (hADSCs) were commercially purchased. These cells were cultured in DMEM medium containing 10 % fetal bovine serum and 1 % penicillin-streptomycin antibiotic. Based on a sequential extraction method, n-hexane (Hex), ethyl acetate (EtAc), and ethanolic extracts were obtained from the seeds of F. vulgare. To prepare the F. vulgare extract nanoemulsion, the aqueous phase (distilled water), the oily part (F. vulgare extract), Span 80 and Tween 20 were used. The optimal dose of F. vulgare nanoemulsion was determined using the MTT assay and acridine orange/ethidium bromide (AO/EB) staining. Neural differentiation was induced using a specialized differentiation medium on the MSCs, with the prepared nanoemulsions acting as inducers. The neural differentiation of the human differentiated hADSCs was studied and evaluated through Real-time PCR and immunocytochemistry (ICC) techniques on days 7 and 14.

Results

The results obtained from the MTT and AO/EB tests indicated that the optimal dose of F. vulgare nanoemulsions is 1 μg/ml. Analysis of neural differentiation index gene expression revealed a significant (P ≤ 0.05) upregulation of MAP-2, β-tubulin III, and NSE genes on days 7 and 14 following treatment with the nanoemulsions. It is noteworthy that the nanoemulsion prepared from the hexane extract of the plant showed a significant increase in the expression of marker genes in the process of neural differentiation. Protein expression analysis demonstrated an increase in MAP-2, β-tubulin III, and NSE (gamma enolase) proteins in response to the nanoemulsion inducers compared to the control group (TCPS).

Discussion

Overall, our findings indicate that F. vulgare nanoemulsions have a positive effect on the expression of genes and proteins related to neural differentiation in hADSCs. The proposed protocol may serve as a potential therapeutic strategy in complementary medicine for patients seeking to improve injuries to the nervous system. However, further studies and performance measurements are necessary in future research to confirm these results.

期刊介绍： Tissue and Cell is devoted to original research on the organization of cells, subcellular and extracellular components at all levels, including the grouping and interrelations of cells in tissues and organs. The journal encourages submission of ultrastructural studies that provide novel insights into structure, function and physiology of cells and tissues, in health and disease. Bioengineering and stem cells studies focused on the description of morphological and/or histological data are also welcomed. Studies investigating the effect of compounds and/or substances on structure of cells and tissues are generally outside the scope of this journal. For consideration, studies should contain a clear rationale on the use of (a) given substance(s), have a compelling morphological and structural focus and present novel incremental findings from previous literature.
